TECHNICAL FIELD

Embodiments of the present disclosure relates to the field of computer technology, specifically to the field of Internet technology, and more specifically to a method and an apparatus for processing information.

BACKGROUND

Whether in daily life or at work, a large amount of text is exposed. A text message may contain various information. How to process text information is an urgent technical problem for those skilled in the art.

It should be appreciated that the numbers of the terminal devices, the network and the server in FIG. 1 are merely illustrative. Any number of terminal devices, networks and servers may be provided based on actual requirements.

Further referring to FIG. 2 , a flow 200 of an embodiment of a method for processing information according to the present disclosure is illustrated. The method includes the following steps 201-205.

Step 201 includes acquiring a word sequence obtained by performing word segmentation on two paragraphs in a text, where the word sequence includes at least one specified identifier for replacing a word.

In this embodiment, the execution body of the method for processing information (such as the server or the terminal devices shown in FIG. 1 ) may acquire the word sequence corresponding to the two paragraphs in a text from the local or other execution body. Specifically, the execution body or other execution body may perform word segmentation on the two paragraphs in the text to generate an initial word sequence, and then replace at least one word in the initial word sequence with a specified identifier, thereby generating the word sequence. The specified identifier herein may mask the replaced words and thus may be used to train the natural language processing model to predict missing words based on context. A specific character may be used to connect respective words sequences of the two paragraphs.

Step 202 includes inputting the word sequence into a to-be-trained natural language processing model to generate a word vector corresponding to a word in the word sequence, where the word vector is used to represent the word in the word sequence and a position of the word.

In this embodiment, the execution body may input the word sequence into the to-be-trained natural language processing model, thereby using the natural language processing model to generate the word vector corresponding to each word in the word sequence. The position of the word herein may be the position of the word in the word sequence, such as sequencing, or the paragraph where the word is located. For example, the natural language processing model herein may be a word embedding model such as seq2seq models or word2vec.

In practice, the execution body may generate the word vector that represents both the word itself and the position of the word in various ways. For example, the execution body may determine the position information corresponding to the position of the word in the word sequence, and determine the vector corresponding to the position information. In addition, the execution body may determine the vector corresponding to the word. Then, the execution body may splice the two vectors to obtain the word vector.

In some alternative implementations of this embodiment, the step 202 may include: inputting the word sequence into an embedding layer of the to-be-trained natural language processing model; converting, for the word in the word sequence, the word into an identifier of the word through the embedding layer, and converting the identifier of the word into a first vector; converting position information of the word in the word sequence into a second vector through the embedding layer; determining paragraph position information indicating a paragraph where the word is located in the two paragraphs through the embedding layer, and converting the paragraph position information into a third vector; and splicing the first vector, the second vector, and the third vector to obtain a word vector corresponding to the word.

In these alternative implementations, the execution body may use the embedding layer to generate the word vector. Specifically, for the word in the word sequence (such as each word in the word sequence), the execution body may look up the identifier corresponding to the word in a word list in the embedding layer. Then, the execution body may convert the identifier of the word into a vector, and use the vector as the first vector. In addition, the execution body may convert the position information of the word in the word sequence into a vector in the embedding layer, and use the vector as the second vector. Also, the execution body may determine, in the embedding layer, the paragraph where the word is located in the two paragraphs, that is, the paragraph position information. Specifically, a specified character may be used as the paragraph position information to indicate the paragraph where the word is located, for example, an EA may be used to indicate that the word is located in the first paragraph in two paragraphs, and an EB may be used to indicate that the word is located in the second paragraph, where both the EA and the EB are the paragraph position information. Thereafter, the execution body may convert the paragraph position information into a vector, and use the vector as a third vector. Specifically, the vectors obtained by the three transformations may be low-dimensional vectors. Then, the execution body may splice the obtained first vector, second vector, and third vector to obtain the word vector corresponding to the word.

The word vectors in these implementations may represent the word, the position information of the word in the word sequence, and the paragraph where the word is located, so that various properties of the word may be accurately and comprehensively expressed by the word vectors.

Step 203 includes inputting the word vector into a preset processing layer of the to-be-trained natural language processing model, where the preset processing layer includes an encoder and a decoder.

In this embodiment, the execution body may input the word vector to the preset processing layer of the to-be-trained natural language processing model. The preset processing layer herein may include the encoder and the decoder. The execution body may use the encoder to read an input word vector and encode it into an intermediate representation. Then, the execution body may use the decoder to further process the intermediate representation and output the processed word vector.

In some alternative implementations of this embodiment, the preset processing layer includes a plurality of cascaded preset processing layers; and the step 203 may include inputting the word vector into a first preset processing layer of the plurality of cascaded preset processing layers.

In these alternative implementations, the natural language processing model may include a plurality of preset processing layers, which may be cascaded. That is, the result of the previous preset processing layer is input to the posterior preset processing layer. The execution body may input the word vector to the first preset processing layer, so that the first preset processing layer transfers the result to the posterior preset processing layer after processing, and the posterior preset processing layer may execute processing based on the result of the first preset processing layer, and so on until the last preset processing layer is processed.

These implementations may use the plurality of cascaded preset processing layers to execute multi-step processing, thereby improving the accuracy of the processing.

In some alternative implementations of this embodiment, the preset processing layer includes a plurality of processing units including an encoder and a decoder. In the plurality of cascaded preset processing layers, the result of each processing unit of the previous preset processing layer is input to processing units of the posterior preset processing layer.

In these alternative implementations, each preset processing layer may include a plurality of processing units, for example, the processing units herein may be transformer units. Each processing unit may include an encoder and a decoder, for example, may include six encoders and six decoders. The result of each processing unit in the previous preset processing layer may be input to all the processing units of the posterior preset processing layer.

In these implementations, each processing unit of the posterior preset processing layer may obtain the results of all the processing units of the previous preset processing layer, so that the respective results may be comprehensively fused.

Step 204 includes predicting whether the two paragraphs are adjacent, and a replaced word in the two paragraphs, to obtain a prediction result, based on a processing result output by the preset processing layer.

In this embodiment, the execution body may use the processing result output by the preset processing layer in the natural language processing model to predict whether the two paragraphs are adjacent in the text, thereby predicting adjacent information indicating whether the two paragraphs are adjacent, and may predict which word is replaced with the specified identifier.

Step 205 includes acquiring reference information of the two paragraphs, and training the to-be-trained natural language processing model to obtain a trained natural language processing model, based on the prediction result and the reference information, where the reference information includes adjacent information indicating whether the two paragraphs are adjacent or not, and the replaced word.

In this embodiment, the execution body may acquire the reference information of the two paragraphs, and train the to-be-trained natural language processing model based on the prediction result obtained by the prediction and the reference information. Specifically, the reference information is real data present in the text. Whether the two paragraphs are adjacent and which word is replaced are objective, thus the reference information may be obtained without manual labeling. The execution body may use the preset loss function, the reference information and the prediction result, to calculate the loss value. In practice, the loss value may be the sum of two sub-loss values, where the one sub-loss value thereof corresponds to the adjacent information and the other sub-loss value thereof corresponds to the replaced word.

The method provided in the embodiment of the present disclosure may use a large number of samples without manual labeling to train a natural language processing model, so that the problem of insufficient samples may be solved and the prediction accuracy of the model may be improved, while the manpower consumption is reduced.

In some alternative implementations of this embodiment, the method may further include: acquiring second sample information, where the second sample information includes a second paragraph word sequence obtained by performing word segmentation on a second target paragraph, and a second specified attribute, where an attribute matching the second specified attribute is included in the second paragraph word sequence, where the attribute matching the second specified attribute completely or partially matches the second specified attribute; inputting the second sample information into the trained natural language processing model, and predicting an attribute value of the second specified attribute in the second paragraph word sequence; and training the trained natural language model to obtain a second model, based on an predicted attribute value and the attribute value for labeling the attribute completely matching or partially matching the second specified attribute.

In these alternative implementations, the execution body may acquire the second sample information and input the second sample information into the trained natural language processing model, thereby using the trained natural language processing model to predict the attribute value of the second specified attribute in the second paragraph word sequence.

In practice, the attribute matching the second specified attribute in the second paragraph word sequence may completely match or partially match the second specified attribute. For example, the second specified attribute may be “an issue date”, and if the attribute completely matches the second specified attribute, the attribute may be “an issue date”. Otherwise, if the attribute partially matches the second specified attribute, the attribute may be “issued on XX”.

These implementations may train the model to accurately predict the attribute values. By using the complete match and the partial match, not only the attribute values may be found when the attributes are same, but also the attribute values may be found when the meanings of the attributes are same but the expressions are different, thereby improving the recall rate of prediction.

Further referring to FIG. 3 , FIG. 3 is a schematic diagram of an application scenario of a method for processing information according to some embodiments of the present disclosure. In the application scenario of FIG. 3 , the execution body 301 may acquire a word sequence 302, such as “an issuer: Company sep in city A issues a total amount of no more than RMB 500 million Yuan mask” obtained by performing word segmentation on two paragraphs in a text, where the word sequence includes at least one specified identifier “mask” for replacing a word; inputting the word sequence into a to-be-trained natural language processing model to generate a word vector 303 corresponding to a word in the word sequence, where the word vector is used to represent the word in the word sequence and a position of the word; inputting the word vector into a preset processing layer 304 of the to-be-trained natural language processing model, where the preset processing layer includes an encoder and a decoder; predicting whether the two paragraphs are adjacent or not, and a replaced word in the two paragraphs, to obtain a prediction result 305, based on a processing result output by the preset processing layer; and acquiring reference information of the two paragraphs, and training the to-be-trained natural language processing model to obtain a trained natural language processing model 306, based on the prediction result and the reference information, where the reference information includes adjacent information indicating whether the two paragraphs are adjacent or not, and the replaced word.

Further referring to FIG. 4 , yet another flow 400 of an embodiment of a method for processing information according to the present disclosure is illustrated. The flow 400 of the method for processing information includes the following steps 401-408.

Step 401 includes acquiring a word sequence obtained by performing word segmentation on two paragraphs in a text, where the word sequence includes at least one specified identifier for replacing a word.

In this embodiment, the execution body of the method for processing information (such as the server or the terminal devices shown in FIG. 1 ) may acquire the word sequence corresponding to the two paragraphs in a text from the local or other execution body. Specifically, the execution body or other execution body may perform the word segmentation on the two paragraphs in the text to generate an initial word sequence, and then replace at least one word in the initial word sequence with a specified identifier, thereby generating the word sequence. The specified identifier herein may mask the replaced word and thus may be used to train the natural language processing model to predict a missing word based on context. A specific character may be used to connect respective word sequences of the two paragraphs.

Step 402 includes inputting the word sequence into a to-be-trained natural language processing model to generate a word vector corresponding to a word in the word sequence, where the word vector is used to represent the word in the word sequence and a position of the word.

In this embodiment, the execution body may input the word sequence into the to-be-trained natural language processing model, thereby using the natural language processing model to generate the word vector corresponding to each word in the word sequence. The position of the word herein may be the position of the word in the word sequence, such as sequencing, or the paragraph where the word is located.

Step 403 includes inputting the word vector into a preset processing layer of the to-be-trained natural language processing model, where the preset processing layer includes an encoder and a decoder.

In this embodiment, the execution body may input the word vector to the preset processing layer of the to-be-trained natural language processing model. The preset processing layer herein may include the encoder and the decoder. The execution body may use the encoder to read an input word vector and encode it into an intermediate representation. Then, the execution body may use the decoder to further process the intermediate representation and output the processed word vector.

Step 404 includes predicting whether the two paragraphs are adjacent, and a replaced word in the two paragraphs, to obtain a prediction result, based on a processing result output by the preset processing layer.

In this embodiment, the execution body may use the processing result output by the preset processing layer in the natural language processing model to predict whether the two paragraphs are adjacent in the text, thereby predicting adjacent information indicating whether the two paragraphs are adjacent, and may predict which word is replaced with the specified identifier.

Step 405 includes acquiring reference information of the two paragraphs, and training the to-be-trained natural language processing model to obtain a trained natural language processing model, based on the prediction result and the reference information, where the reference information includes adjacent information indicating whether the two paragraphs are adjacent or not, and the replaced word.

Step 406 includes acquiring first sample information, where the first sample information includes a first paragraph word sequence obtained by performing segmentation on a first target paragraph, and a first specified attribute.

In this embodiment, the execution body of the method for processing information (such as the server or the terminal devices shown in FIG. 1 ) may acquire the first sample information from the local or other electronic device. The first sample information herein may include a first paragraph word sequence corresponding to the first target paragraph, and a first specified attribute. The first target paragraph may include an attribute and an attribute value of the attribute, for example, the attribute is gender and the corresponding attribute value is female. The first specified attribute may or may not be related to the first target paragraph. The paragraph word sequence herein may not include the specified identifier for replacing the word.

Step 407 includes inputting the first sample information into the trained natural language processing model to predict correlation information, where the correlation information is used to indicate a correlation between the first paragraph word sequence and the first specified attribute.

In this embodiment, the execution body may input the first sample information into the trained natural language processing model to predict the correlation information. The correlation information herein is used to indicate the correlation between the first paragraph word sequence and the first specified attribute. For example, the correlation information may be a correlation value for quantifying correlation, or may be specific information for reflecting the correlation levels, e.g., the specific information may indicate such as “correlated”, “uncorrelated”, or “very correlated”, “general correlated” and “not correlated” respectively.

In practice, if the first specified attribute is completely presented in the paragraph, the corresponding correlation value may be the maximum value. If there is an attribute with the same meaning as the first specified attribute in the paragraph, the correlation value may be decreased compared to the maximum value. If there is an attribute with the partially same meaning as the first specified attribute in the paragraph, the correlation value may be decreased compared to the maximum value. If there is no same or similar words as the first specified attribute in the paragraph, the correlation value may be much lower than the maximum value, for example, may be the minimum value.

Step 408 includes training the trained natural language processing model to obtain a first model, based on predicted correlation information and correlation information for labeling the first sample information.

In this embodiment, the execution body may acquire the correlation information for labeling the first sample information. In this case, the execution body may calculate a loss value based on the labeling correlation information and the predicted correlation information to implement the further training of the trained natural language processing model, thereby obtaining the first model.

This embodiment may combine the labeled and unlabeled samples to execute a comprehensive training, thereby further improving the accuracy of the model.

In some alternative implementations of this embodiment, the method may further include: acquiring second sample information, where the second sample information includes a second paragraph word sequence obtained by performing word segmentation on a second target paragraph, and a second specified attribute, where an attribute matching the second specified attribute is included in the second paragraph word sequence, and the attribute matching the second specified attribute completely or partially matches the second specified attribute; inputting the second sample information into the trained natural language processing model, and predicting an attribute value of the second specified attribute in the second paragraph word sequence; and training the trained natural language model to obtain a second model, based on an predicted attribute value and an attribute value for labeling the attribute matching the second specified attribute.

In these alternative implementations, the execution body may acquire the second sample information and input the second sample information into the trained natural language processing model, thereby using the trained natural language processing model to predict the attribute value of the second specified attribute in the second paragraph word sequence.

In practice, the attribute matching the second specified attribute in the second paragraph word sequence may completely match or partially match the second specified attribute. For example, the second specified attribute may be “an issue date”, and if the attribute completely matches the second specified attribute, the attribute may be “an issue date”. If the attribute partially matches the second specified attribute, the attribute may be “issued on XX”.

It should be noted that the acquired samples for training the trained natural language model to obtain the first model and the second model, may be completely same or partially same, and thus, “the first sample information” and “the second sample information”, “the first target paragraph” and “the second target paragraph”, “the first specified attribute” and “the second specified attribute” and “the first paragraph word sequence” and “the second paragraph word sequence” may be completely same.

These implementations may train the model to accurately predict the attribute values. By using the complete match and the partial match, not only the attribute values may be found when the attributes are same, but also the attribute values may be found when the meanings of the attributes are same but the expressions are different, thereby improving the recall rate of prediction.

In some alternative application scenarios of these implementations, the predicting an attribute value of the second specified attribute in the second paragraph word sequence, may include: predicting position information of the attribute value of the second specified attribute in the second paragraph word sequence, where the position information includes start position information and end position information.

In these alternative application scenarios, the predicted value may represent the position information in the paragraph word sequence. For example, the word sequence corresponding to the attribute value is “no more than RMB 500 million Yuan”, and the execution body may label “no” and “Yuan” as the start position and the end position, and use the information for labeling the two position as the start position information and the end position information.

These application scenarios may use the start position information and the end position information to accurately represent the attribute value by using little information.

In some alternative application scenarios of these implementations, the method may further include: acquiring a text word sequence obtained by performing word segmentation on a target text, and dividing the text word sequence into a plurality of paragraph word sequences; determining paragraph word sequences associated with a target attribute from the plurality of paragraph word sequences; inputting the target attribute and the determined paragraph word sequences into the first model, and predicting correlation information between the target attribute and each of the determined paragraph word sequences, where the correlation information includes a correlation value; selecting a preset number of paragraph word sequence from the determined paragraph word sequences in a descending order of the correlation values; inputting the target attribute and the preset number of paragraph word sequence into the second model, and predicting an attribute value of the target attribute and a confidence level of the attribute value of the target attribute for the preset number of paragraph word sequence; and determining an attribute value of the target attribute from the predicted attribute value of the target attribute, based on the correlation value and the confidence level.

In these alternative application scenarios, after obtaining the first model and the second model by training, the execution body may use the two models to predict the attribute value of the target attribute in the text. Specifically, the execution body may acquire the word sequence corresponding to the target text as the text word sequence, and divide the text word sequence into a plurality of paragraph word sequences according to the segmentation granularity of the paragraphs. Each paragraph word sequence corresponds to a paragraph in the target text. Then, the execution body may execute an initial screening on the plurality of paragraph word sequences, filter out the paragraph word sequences completely unrelated to the target attribute, and determine the paragraph word sequences related to the target attribute.

Then, the execution body may input the target attribute and the determined paragraph word sequences into the first model, in order to use the first model to predict the correlation information between the target attribute and each of the determined paragraph word sequences (in the initial screening). The correlation information herein may be a correlation value, and a larger value indicates a larger correlation. Thereafter, the execution body may select a preset number of paragraph word sequence from the plurality of determined paragraph word sequences in a descending order of the correlation values. For example, in the determined paragraph word sequences, the paragraph word sequences with top 3 correlation values are selected. Specifically, the selecting step may be executed by the execution body in the first model, or may be executed outside the first model.

Then, the execution body may input the target attribute and the preset number of paragraph word sequence into the second model, thereby using the second model to predicting the attribute value of the target attribute and the confidence level of the attribute value from the preset number of paragraph word sequence.

After obtaining the output correlation values from the first model and the output confidence levels from the second model, the execution body may determine the attribute value of the target attribute from the predicted attribute values of the target attribute based on the correlation values and the confidence levels.

In practice, the execution body may determine the attribute value based on the correlation values and the confidence levels in various ways. For example, the execution body may directly obtain the correlation values between the target attribute and the paragraph word sequence where the attribute value is located for each of predicted attribute values of the target attribute. The correlation values obtained herein are previously predicted by the execution body using the first model. Then, the sum of the acquired correlation value and the confidence level of the attribute value is determined. Finally, the attribute value, of which the corresponding sum is maximum, in the predicted attribute values of the target attribute is determined as the attribute value of the target attribute. In addition, the execution body may input the obtained correlation value and the target attribute into a preset model, and the model may represent the corresponding relationship between the combination of the correlation value and the attribute, and the attribute value. In this case, the execution body may obtain the attribute value of the target attribute output by the model.

These application scenarios may use the first model and the second model obtained by training to accurately determine the attribute value, thereby implementing the accurate extraction of the key information.

Alternatively, in the application scenario, the determining an attribute value of the target attribute from predicted attribute values of the target attribute, based on the correlation values and the confidence levels, may include: determining, for each attribute value of the predicted attribute values of the target attribute, a product of a correlation value between a paragraph word sequence where the attribute value is located and the target attribute, and a confidence level of the attribute value; and determining an attribute value corresponding to a maximum product from the predicted attribute values of the target attribute as the attribute value of the target attribute.

In these alternative application scenarios, the execution body may determine the product of the correlation value and the confidence level corresponding to the attribute value. Then, the execution body may determine the maximum product, and use the attribute value corresponding to the confidence level used in calculating the maximum product as the attribute value of the target attribute.

These alternative application scenarios may be completely used by multiplying the confidence level with the correlation value to obtain the more accurate attribute value.

Alternatively, the determining a paragraph word sequence related to a target attribute from the plurality of paragraph word sequences, includes: determining, for each of the plurality of paragraph word sequences, whether a word matching the target attribute is included in the paragraph word sequence; and determining the paragraph word sequence as the paragraph word sequence related to the target attribute, if the word matching the target attribute is included in the paragraph word sequence.

In these alternative application scenarios, the execution body may determine whether a word completely matching or partially matching (i.e., matching) the target attribute is included in the plurality of paragraph word sequences. It is determined that the paragraph word sequence is related to the target attribute, if the word matching the target attribute is included in the paragraph word sequence.

In these application scenarios, matching may be used to execute a relatively fast and accurate initial screening of the paragraph word sequence, thereby shortening the prediction time of the subsequent natural language processing model.
